'The hunted one' now on run for 100 days

South Island celebrity fugitive William Stewart has reached 100 days as "the hunted one".

Stewart has been wanted by police since October but the pursuit began in earnest in February when he allegedly threatened a police officer with an iron bar.

He is thought to be living rough around rural Canterbury, committing burglaries and stealing vehicles as required.

He last surfaced at the beginning of the month when a truck was stolen from a Staveley property, 42km northwest of Ashburton.

Since then the trail had gone cold, Senior Sergeant Stewart Munro told The Press.

"Where he is we just don't know."

Stewart has achieved infamy for his efforts at evading capture, making international headlines and gaining fans on a FaceBook page.

An Ashburton property developer was selling "Where's Billy" t-shirts on Trade Me while a Timaru man wrote a song about him.

Police are less enamoured with Stewart, pointing out he was thought to have committed a string of burglaries and car thefts, was a P-addict and possibly armed.
